Description

Edging for grids, especially for wire mesh fences The invention relates to an edging for grids, in particular for wire mesh fences, with a profile element encompassing a grid edge with mutual locking edges.

The purpose of the invention is wire mesh, especially for fences, in a simple manner Type of edging without a weld, which acts as a support for the Fence grid fixed the same.

Wire mesh fences are made by the locksmith. Should such a Fence are created, the necessary for the inclusion of the fence post must first Brickwork precede. The fence front is divided into post spacing. These post spacings are called fields, they are different in length for each fence. That is why the wire grids for these folds are made to measure, in plate form, required and manufactured. Because now the edges of these grids have loose ends, they become with Iron frame bordered, with fence posts and frames with tabs to screw with each other.

In addition to angle and flat bars, steel tubing is usually used for these frames used. When using steel tubing, the grilles are in the finished frame butt welded electrically, wire by wire. Or they are made by drilling Holes on the inside of the 4 frame parts inserted into them and only then to Rahms welded together.

If angle or flat iron is used for the frame, the Grids also electrically welded in or dotted, or they are with a 2nd frame made of flat iron covered and riveted.

Such fences are very beautiful and durable, but the production is The same is still very wage-intensive and therefore makes it much more expensive. In addition the rust protection to be applied and the maintenance costs that are also high.

The manufacture of these, which is associated with a lot of welding work, also has Wire mesh fences a use of plastic-coated wires, for these grids, prevented to this day because of their damage during further processing.

The patent number 111 070 class 37 (enclosures) is known.

A slotted tube is used, in the slot of the length after, square wire mesh is inserted. Around your wire mesh in your slotted pipe To provide a hold, must be knot-like at the top and bottom of the braid Thickenings are attached.

This slotted tube could also be used for wire mesh.

However, it can only be pushed open lengthways, horizontally.

In order to achieve its purpose, the slot in the pipe would have to fit, The consequence of this would be that the pipe would not be able to be pushed open, or would be very difficult to push. Using plastic-coated wire mesh would damage the same. Wanted to if you put on this slit tube from above, the slit should be so wide that the grating had no hold in it. Pressing together would be without equipment not possible at all.

The invention overcomes these disadvantages. It is made from a slotted pipe further developed, inden the two slot edges angled inwards at an angle to each other are. This creates a wedge-like pile that is pressed open by springing apart on the Citterrsnd guaranteed. If this profile element is over the 1st length wire of the grille, it springs back and locks into place along its long edges behind the same that an absolutely reliable connection has been established.

The task of the invention is set: The activity and material consuming To circumvent frame edging d.r wire mesh in the conventional way, inde. same no longer in purlins, but en a bit off the roll is used. According to the invention, the profile element is placed on the upper edge of the grid attached and fastened to the fence post so as to carry the wire mesh and to give it a solid edge. This makes it possible to use a wire mesh fence a very considerable saving in labor and material.

This task is solved in that for the beveling of the Wire mesh a resiliently encompassing the mesh edge with the protruding mesh elements, in the direction transversely to the grid edge, provided on both sides locking profile element is.

This profile element consists of a slotted tube made of steel with an ellipsoidal shape Uusrachnitt.1, the slit edges 2 + 3 inclined inwards parallel to each other are angled and snap into place behind the protruding grid elements. -With The advantages achieved by the invention are considerable. This eliminates the need for time-consuming edging the lattice in iron frame.

All types of wire fencing can be used, in particular also plastic-coated.

The wire mesh is used in one piece off the roll and are therefore cheaper than made to measure in panels. The whole Fence can be made and installed without welding. This gives the opportunity to use plastic-coated material for all fence parts. That’s the fence largely maintenance-free. The whole fence is kept so simple by the invention, that it can be assembled by anyone without prior knowledge in the shortest possible time is.

The assembly proceeds as follows: When the fence posts are set in concrete and are dry, the wire mesh is unrolled and placed against the posts. So that it stays in place, it is tied to every 2nd post in the middle of the trofisoriach.

Now the profile element, which can have different lengths, is up to approx. 4 m and is tapered at one end, attached to the wire mesh edge from above. This is done by hitting the profile element with a wood or cummi hammer, from the beginning gradually to the end.

If the next following profile element is then attached, one pushes it back lengthways over the taper of the previous one. It is created like this a connection or a joint, as is used with stove pipes. This is how the The entire length of the fence is provided with the profile element and is now ready to be fastened to the fence post. This is done by means of the wire hooks 6, 7 + 8 of FIG. 2. The same are put through the existing holes in the fence post and turned over at the back.

The same border can of course also be used on the lower edge of the grid be attached. However, holes would then have to be made on the profile element for the water to drain off to be available.

The wire mesh for this fence comes with a double top and bottom Edge 4 + 5, Fig. 1 + 2, made to prevent the wires from tearing out during shipping to prevent.

The drawing shows in Fig. 1 the front view of the wire mesh fence with the double grid edges 4 + 5.

In Fig. 2, the section A-B is shown on a scale of 1: 1.

you ht the profile element 1, the two Verrastungrkanten 2 + 3, the double grid edges 4 + 5, as well as the fastening hooks 6, 7 + 8.
